Study on 'Chu-Suk'(VI) -Prosapogenin in Pods of Gleditschia officinalis-

From the crude saponin obtained from the pods of Gleditschia officinalis seven spots were identified by TLC and quantity of gleditschia B was the highest among them. Ten kinds of prosapogenins were identified from the partial hydrolysates of crude saponin and found that prosapogenin E contain oleanolic acid as a sapogenin and prosapogenin F does echinocystic acid as the sapogenin. Hydrolysis of crude saponin yield glucose and rhamnose and the same sugar were also identified from the mixture of prosapogenin E and F.
